15 Claims.

The invention relates to new and. useful improvements in a nozzleattachment for filling tanks and more particularly a nozzle attachmentwhich is adapted to be detachably connected to an intake housing in thebottom wall of a tank.

An object of the invention is to provide a nozzle attachment whichincludes an inner sleeve connected to the supply and an outer sleeveprovided with means cooperating with devices on the tank intake housingfor securing the inner sleeve in sealed engagement with said tankhousing.

A further object of the invention is to provide an attachment of theabove type wherein the nozzle is equipped with a manually operated valvefor controlling the flow of fluid from the nozzle into the tank.

A further object of the invention is to provide a locking means forpreventing the opening of the nozzle valve until the attachment isconnected in sealed engagement with the tank intake housing.

A still further object of the invention is to provide a locking meansfor preventing detaching of the nozzle until the nozzle valve has beenmoved to closed position.

These and other objects will in part be obvious and will in part behereinafter more fully described.

Figure 5 is a sectional view on the line 55 of Figure 4; and

Figure 6 is a sectional view on the line 6-6 of Fig. 4.

For the purpose of securing the nozzle attachment to the tank, said tankis provided with an intake housing having an inlet opening leading tothe tank with which a valve is associated for closing the inlet when thenozzle is detached from the tank housing. The nozzle includes an innersleeve which is adapted to be connected in sealed engagement with thetank housing. There is an outer sleeve rotatably secured to the innersleeve for detachably connecting said inner sleeve to the tank housing.This inner sleeve is connected to the fluid supply. Within the nozzle isa valve for closing the passage leading through the nozzle. The valveopens outwardly in the present embodiment of the invention and ispositioned .and dimensioned so that when the valve is moved to openposition it will contact the inlet valve in the tank housing and forcethe same to open position.

There is means associated with the nozzle for manually opening thenozzle valve and there is also means associated with the nozzle whichprevents the opening of the nozzle valve until the nozzle is in sealedengagement with the tank housing. There is likewise a means forpreventing the detachment of the nozzle from the housing until thenozzle valve has been moved to full seated position. I

Referring more in detail to the drawings, a tankto which the improvednozzle attachment is connected is provided with a tank housing I. Thistank housing is preferably secured to the bottom wall of the tank. Thehousing has a flange 3 which engages the outer face of the tank wall andthe flange is secured to the tank wall by means of bolts 4. There is'agasket 5 between the tank wall and the housing for sealing theconnection. The housing is provided with an inwardly projecting portion8 having an opening 9 therethrough. Attached to the under side of thisinwardly projecting portion 8 is an annular member In having a passage ll therethrough and this passage II is surrounded on the upper face ofsaid member ID by an inclined wall I2 forming a valve seat. This annularmember Ill has a depending sleeve l3 carrying projecting lugs l4, I4 towhich the nozzle attachment is connected, as will be hereinafter morefully described.

The annular member I!) issecured to the under side of the inwardlyprojecting portion 8 by suitable bolts l5, l5. There is a gasket I'Bwhich seals the connection between the housing and this annular memberH]. The passage II serves as an inlet passage through which fluid may besupplied to the tank. This passage is controlled by a valve l! which ismounted for vertical movement and a spring 20 normally moves the valveinto engagement with the seat for closing the inlet for the tank. Thenozzle attachment which is adapted to be detachably connected to thetank housing for the filling of the tank includes an inner sleeve 55 andan outer sleeve 51. This inner sleeve is so dimensioned that it fitswithin the sleeve 53 on th tank housing. There is a gasket 56 carried inthe end wall of the sleeve which is adapted to engage the inwardlyextending ledge surrounding the opening H in the tank housing throughwhich the tank is filled. This gasket 56 makes a sealed connectionbetween the inner sleeve of the nozzle and th housing. As noted above,this inner sleeve is connected to the fluid supply 'for furnishing fluidunder pressure. The outer sleeve 5'! is mounted on the inner sleeve sothat it may be rotated thereon. Said outer sleeve is provided with ashoulder 51 adapted to cooperate with a projecting member 51* on theinner sleeve for forcing the sleeve endwise into sealing engagement withthe tank housing. The outer sleeve 5'1 is provided at its outer end witha ring 58 which is fixed to the outer sleeve. The ring is provided witha tapered opening 59 which facilitates th placing of the nozzle on thedownwardly projecting sleeve portion l3 of the tank housing. This ring58 has an inwardly projecting ledge 50 provided at spaced intervals withopenings 6i which are preferably 120 degrees apart (see Figure 2). These7 openings are adapted to receive lugs l4 carried by the sleeve 13 ofthe tank housing. After the lug have passed through these openings 6|,then the outer sleeve is turned in a clockwise direction, as viewed inFigure 2, until the lugs are brought into contact with limiting stop 62carried by the ring 58.

In order to prevent the inner sleeve of the nozzle attachment fromturning on its seat when turned. These keys are shown in Figure '2. The1 keys are so positioned relative to the slots that when the lugs in thehousing are in alignment with the slots in the nozzle, the keys in thenozzle are also in alignment with the slots in the sleeve member [3 ofthe tank housing. Therefore, when 2 the lugs pass through the slots 6!and permit the movement of the inner sleeve into contact with the ledgeon the housing, the keys will enter the slots and thus hold the innersleeve of the nozzle from turning.

The outer sleeve 5'! is provided with two handles 6T, 5'! which may begrasped by the operator to facilitate the placing of the nozzle on thehousing and then the turning of the sleeve to carry the lugs underneaththe inwardly projecting ledge 68. The keys 63 are retained from radialmovement in the slot 54 by a metal band 68. The keys are held in theslots with a limited longitudinal movement by plates 69, which platesare secured to the outer sleeve by means of screws 19 (see Figure 2).The outer sleeve 51 has an inwardly projecting ledge "II and beneath theledge is a groove 12. The ledge is provided with slots 14. There arethree slots which are in alignment with projecting portions 13 on thekeys when the sleeve is in a position for the detaching of the nozzlefrom the tank. The projections '53 will therefore enter the slots 14 andprevent the sleeve from being turned. When, however, the nozzle isattached to the tank, the keys will enter the slots 56 and these keysand slots are so dimensioned that the seating of the inner sleeve willmove the projections 13 on the keys out of the slot 14 into the groovebeneath the ledge H so that the sleeve is free to return to accomplishthe locking of the nozzle to the tank housing. The inner sleeve 55 has aprojecting portion 51 thereon adapted to be engaged by the shoulder 51on the outer sleeve. This enables the inner sleeve to be forced againstthe seat on the housing when the outer sleeve is turned. The lugs I4have tapered portions l4 which serve as a camming action for drawing theinner sleeve into tight engagement with the seat thereof.

The inner sleeve 55 of the nozzle is provided with a, tapered portionforming a valve seat I5. Avalve 1B is adapted to engage said seat 1'5.Said valve when opened is moved out of the nozzle. The valve is mountedon a stem El which in turn is mounted for reciprocation in a spider 7 8formed integral with the inner sleeve 55 of the nozzle. The valve stem71 is provided with an extension "H of reduced diameter, thus providinga shoulder 19. A rack member has an offset sleeve portion 8| providedwith an opening through which the valve stem extension Fl passes. Aspring 82 abuts at one end against the offset sleeve 8! of the rackmember 80 and at its other end against a nut threaded on to the valvestem extension. There is suflicient clearance between the shoulder 19and the portion 8!, when the valve is closed, so that the spring pressesthe valve against its seat. Said rack member 80 is provided with a rack85 with which a gear 86 meshes. This gear is carried by the shaft 81mounted in bearings carried by the inner sleeve 55. When the shaft isrotated in a clockwise direction, as viewedin Figure l, the valve 56will be moved away from is seat and when the shaft is rotated in theopposite direction, then the valve will be brought in contact with itsseat. Any further movement of the shaft will compress the spring 82 andmerely hold the valve firmly seated.

Mounted on the outer end of the shaft 81 is a collar 88. The collar hasa semi-cylindrical portion 89 and a flat portion 90. The sleeve 5l has alaterally projecting lug provided with a flat face 5! lying in a planeat right angles to the axis of the inner sleeve 55. When the fiat faceof the lug 57 is opposed to the flat face 95 of the collar 88, thenthe'shaft 81 cannot be turned, as the collar is pinned to the shaft.This flat portion 5'? on the sleeve is so disposed that the flatportions are positioned relative to each other, as shown in Figure 4',when the nozzle is first attached and before the outer sleeve is turnedfor locking the inner sleeve to the housing. When this outer sleeve isturned for securing the inner sleeve in sealed engagement with thehousing, the flat portion 5% will move out of range of the fiat portion95. This flat portion 5% is so dimensioned'that the outer sleeve must beturned so as to firmly lock the inner sleeve in firm engagement with thetank housing before the shaft 87 can be turned for opening the valve 15.Assuming that the flat portion 5% has been moved from engagement withthe hat portion and that the valve has been opened by the turning of theshaft 81, this will bring the semi-circula1r portion 89 on the collar 88so it will lie in the path of movement of the projectionportion carriedby the outer sleeve. Therefore the outer sleeve cannot be turned fordisconnecting the nozzle from the tank housing until the nozzle valvehas been moved to .fully seated position and the flat por- .tion 90 ofthe collar 88 placedas shown in Figure 4. This will permit the sleeve tobe turned. When the nozzle is detached from the housing, the lugs 13 onthe keys which are moved endwise by the springs 55 will be seated in thenotches 14 and therefore the outer sleeve 51 cannot be turned on theinner sleeve so as to move the fiat portion 99 of the collar from itsposition opposed to the flat section 96 on the lug, and this willprevent any possible opening of the nozzle valve accidentally when thenozzle is detached from the tank housing.

When it is desired to fill the tank, the nozzle is attached to the tankhousing and the outer sleeve turned so as to firmly secure the innersleeve in sealed engagement with the housing. Then the shaft controllingthe nozzle valve is free tobe turned, as the fiat section 5'1 on theouter sleeve is moved out of contact with the flat section 90 on thecollar 88 pinned to the shaft 81.

In the present embodiment of the invention, as the nozzle valve is movedaway from its seat, it'is so dimensioned that it passes through theopening H and contacts with the inlet valve 1? and lifts it fromitsseat, compressing the spring 2!]. After these valves are moved toopen position, the fluid under pressure is directed from the hoseconnected to the inner sleeve through the inlet opening into the tank.After the tank has been filled, the shaft 8? is turned so as to closethe nozzle valve and this will permit the inlet valve also to move toclosed position. It is onl when the nozzle valve has been fully seatedthat the flat :face 98 on the sleeve 88 is brought into alignment withthe flat face 57 on the outer sleeve and this permits the outer sleeveto be turned for the disconnecting of the nozzle from the tank housing.

Attached to the shaft for turning the same is a crank 9|. This crankextends diametrically across the axis of the shaft and projects fromeach side of the shaft. One of the outer ends of the crank is providedwith a sleeve s2 and mounted in the sleeve for endwise movement thereinis a locking pin 93. A spring 93 disposed in a recess in the sleevebears at one end against a member rigid with the locking pin and at itsother end against the bottom of the recess. lhis normally forces the pinout of the sleeve. A handle member 95 is attached to the pin. Thishandle member telescopes in part thesleeve and contacts with a shoulderon the sleeve so as to limit the outward movement of the pin. The handleserves as a means for moving the pin so as to retract it into thesleeve. There is a locking plate 98 secured to the inner sleeve 55. Saidlocking plate at one side thereof carries a stop 91 with which the crankwill contact to limit the turning movement of the shaft. It also isprovided with a cam face Q8 so that when the crank arm is turned to aposition for closing the valve, the locking pin 93 will engage saidinclined face, and this will lift the pin until it is brought intoregister with the opening 55 in the plate 95. When the pin 93 is inregister with the opening, the spring will force the same into theopening and this will lock the crank from turning in either direction.The pin and opening are so disposed relative to the flat side $39 thatwhen the pin is in the opening, the fiat side will be in alignment withthe flat side 51* so as to permit the sleeve 5'! to :be turned when thenozzle is to be detached from the tank housing. At the other end of thecrank arm 9| is a sleeve 92 in which a locking pin 82 is mounted. Thespring 93 forces'the pin. outof the sleeve. A handle member I00 isattachedto the locking pin 92 The plate 95 is provided with an inclinedportion IHI and a stop I02. When the shaft is turned so as to open thevalve, the pin 93 Will engage the inclined surface HH and be retracted,and then when not registering with the opening 98*, it will be movedinto said opening and lock the crank from turning. In order to turn thecrank to close the valve, the operator grasping the handle I00 lifts thepin from the recess and then the shaft can be turned so far as thesemanually operated locking devices are concerned.

However, as noted above, the shaft cannot be turned for opening thevalve until the nozzle is attached in sealing engagement with thehousing and the outer sleeve on the nozzle cannot be turned fordetaching the nozzle until the valve has been moved to closed position.Furthermore, the outer sleeve cannot be turned on. the inner sleeveafter the nozzle has been detached, as the keys will prevent thisoccurrence.

This nozzle attachment for filling atank may be used in connection witha manually opened inlet valve associated with the filling opening forthe tank. It may likewise be used in connection with a fluid pressureactuated inlet valve.

The nozzle attachment may not only be used for the filling of a tank,but also in connection with the draining of the tank and has particularadvantages when so used, as fully shown and described in my co-pendingapplication, Serial No. 751,488 filed Ma 29, 1947.

It is obvious that many changes in the details of construction andarrangement of parts may be resorted to without departing from thespirit of my invention as set forth in the appended claims.
